The usual quilting or stitching feetdfor sewing machines serve mainly for producing ordmary seams. If seams are also to be drawn on the machine at a definite accurate 6 distance from the edgeof the material, supplementary devices must be fitted to the quilt ing foot,..for instancea so-called guide or rule. It is already known to secure to the quilting foot, in place or" such a guide, two or 1 more supplementaryguiding limbs besides the ordinary pressing limbs. These limbs can be shifted laterally and in a vertical direction, so that they permit of guidance on the edge of the material.

known in which the limbs themselves are arranged separately and rockably.

It is a disadvantageof all the known constructions that it is not possible, with one and the same device, to make quite narrow edge seams (1 millimetre) and. so-called blind stitches, and also seams at a considerable distance from the edge. On the one hand the additional limbs, which guidealongthe edge of the material, cannot be shifted close up to 25 the needle, because the side limb of the quilter itself is located in between,'and on the other hand the lateral movability of the rock able limbs is not sufficient for a greater distance. Furthermore it is inconvenient that #9 for the adjusting of the quilting foot to a definite breadth of the seams a number of screws have to be loosened and tightened again.

This invention relates to a universal quilting toot, which enables quite narrow and also broad edge seams to be produced. This is rendered possible by the fact that both limbs are separated from the foot and are so fitted as to be laterally displaceable. In order to enable guidance along the edge of the material to be effected alternately 011 the right and on the left, the limbs can furthermore be rotated relatively to one another and relatively to the centre piece of the quilter. In this case the centre piece is so constructed that it only holds the material down immediately behind the needle. I

One example of construction of the qui ter according to this invention is illustrated in the accompanying drawing, in which Quilters are also Figure 1 shows the quilter in an extended condition in perspective, 1

Figure 2 illustratesthe special construction of one movable limb, also in perspective, and a Figure shows themeans for connecting the two limbsof the quilting foot in section.

The centre piece 1, shown in Figure 1, is so constructed at its upperend 10 that it can be secured to the presser bar of a sewing machine like an ordinary quilting foot. The center piece 1 is adapted to act as a presser foot behind the sewing machine needle only.

It furthercomprises at the lower end, on the rear side, transversely to the direction of sewing, a bore 1. Into this bore there fits a cylindrical tubular member 5,'having a lon gitudinal slot 6. This tube 5 is rigidly connectedwith the limb 2. As shown in Figures 2 and 3 the limb 3 is provided with a bore 8a .and with a narrow spoke-like bridgepiece 8 projecting into the bore. A bar 7, rigidly secured to the bridgepieee 8, is located within the tube 5. This special type of fastening enables the piece of tubing 5 to be inserted over the rod? into the bore in the limb 3. The bridgepiece 8 then takes up a position in the longitudinal slot 6 in the tube 5. It is, therefore, possible to displace both limbs longitudinally with respect to the centre piece 1. 0, The limbs can also be rotated relatively to the centre piece.

In order to enable the two limbs also to be rotated relatively to one another, the slot 6 in the tube 5 (Fig. 3) is made so wide that the narrow bridgepiece 8 of the limb 3 can be moved to and fro to some extent in the slot. Relative rotation of the limbs 2 and 3 is thereby rendered possible to a limited extent. For the clamping of the two limbs after rotation 90. and displacement, there serves a thumb screw i 9. When this screw is tightened, the slotted tube'5, in which the rod (accurately fits, is somewhat compressed. Both the tube and the rod are thereby held fast in the bore 4 of I the centre piece 1. Similarly it is also possible to shift the slot 6 of the tube 5 somewhat rearwards. The screw 9 then engages directly in the slot. Upon tightening the screw the rod 7 would thereby be pressed downwards hand or the left hand limb can be guided along the edge of thematerial asrequired.

As compared with the known constructions,

it is a special advantage that-lap -seams,-

shoulder seams for example, can be executed in the sameadirection ofi sewing. The: ob: lique pulling of the material is thereby obviated'.

The invention furthermore-enablesedge distances of 1 millimetre for example-to be accuratelymaintained: Owing to the great-- lateral displaceability of the limbs, the acces sibility of the needle toinspectioircan be widenedyat will which ensures particularly great reliability-"of sewing-. \Vh'at *I claimis:'- 1:, A divided quilting foot for sewin'g'ma:
